Custom Mailer Boxes FAQ

Can I use Mailer Boxes to package food?

While unprinted corrugated cardboard is generally considered safe for food, our boxes have not been reviewed or certified for food safety. The inks used in our HD Print process are safe for indirect contact with food.

We recommend using food safe wraps or other primary packaging to protect food and limit/prevent direct contact with the mailer boxes.

How do I measure the interior dimensions of my mailer box?

With the box open toward you, here's how to get the correct measurements for the inside of the box:

  • The length is measured from the left to right side of the box.
  • The width is measured from the front to the back of the box.
  • The depth is measured from the top to the bottom of the box.

How should I choose between the kraft or white corrugated cardboard options based on my design?

Select kraft corrugated cardboard if you want a rustic, natural-looking brown color to complement your design. This material works best with darker color palettes since the ink is not opaque and the kraft color will bleed thru and impact the print.

White corrugated cardboard can be used for a variety of designs. Both dark and light colors print well on white material, with the premium white producing the move vibrant final print. If you are in doubt, white material is your best bet.

Can I order a sample box?

Of course! We can make you a single custom box with your own design and dimensions. To order, set the quantity to “1” at the top of this page.

Will there be any difference between the sample box and the final full run?

No, there should be no difference between the sample box and the full production run unless you modify the design or configuration. Our sample orders follow the same production process as larger ones.  The primary purpose of the sample box is to allow you to evaluate the material quality and print before placing a larger order.

Can I design my box on the site?

Our online design tool is simple to use and lets you create a custom box design.

If you’d prefer to design in other software we can also provide a dieline template based on your box specs. First, place your order, then a custom template will be generated and you'll be notificed by email when it's ready to download.

Will my mailer box colors match the proof on my screen?

Colors on your finished box may look different than they do on your screen. Screens display color using RGB light, which can produce brighter, more vivid tones than CMYK printing inks, so some shift is normal and expected.

To minimize the difference, submit your artwork in CMYK color mode (conversion guide here) and review your PDF proof carefully before approving. For the most accurate preview, we recommend ordering a sample box before committing to a large run.

Do you include production or technical markings on your boxes?

We use a QR code to speed up the production of your custom boxes. It also helps us track your order better. Don’t worry, the QR code won’t affect the design since it’s not visible once the box is assembled. 

Good news! We now offer Rush Production on custom box orders.
